VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 669,946, dated March 12, 1901.

7 Application filed July 25,1899. Serial No. 725,033. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN O. ROYER, acitizen of the United States of America, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

My invention has reference to ventilators; and it consists of features fully set forth in the following specification and accompanying drawings.

The object of my invention is to provide a ventilator of an improved design and where by the Wind will have access to the chimneyflue no matter in what direction the wind is blowing.

It consists of a central-draft outlet-pipe adapted to be mounted on or fixed to a chimney. Afflxed to this outlet is a corrugated wind guide or conductor of larger diameter than the said outlet and with an air-passage between them at their union. Mounted on this secondary wind-guide is a funnel-shaped cylindrical section, having four inwardly-inclined and upwardly-extended wind-currentinducing conductors, and surmounting these air-conductors is a cap or covering-hood for the entire device.

In the drawings like parts are referred to by marks or figures of a corresponding kind in the different views.

Figure l is a side elevation of my device. Fig. 2 is a vertical section of one-half of same; Fig. 3, a section on line 3a of Fig. 1. Fig. 4 is a top plan; Fig. 5, a section on line 5 6 of Fig. 1. Fig. 6 is a top view with the hood removed.

A is the outlet-conductor for carrying 0d the products of combustion leading from and adapted to be mounted on the top of a chimney.

B is the corrugated wind-guide, held to the conductor A by the supports b therefor.

O is the secondary wind-guide. This latter guide is secured by intermediate supports 6 to theimember B, as shown in Fig. 2 only. Mounted on the guide 0 is an integral or rigid upwardly-expanding air-conductor D, circular in cross-section at its contact with the guide 0. At its upper end it has four extensions or wings q 0 O 0. These extensions are inclined l t i y these depressions or inward from the upper terminus of the conductor D, forming thereby a series of four wind-guides and draft-assisting wings. In Fig. 6 these wings are best shown. The fact of there being four of these wings enables the device to catch the wind no matter from what part of the compass it may be blowing, and it will be understood for purposes of draft it is not necessary that the wind should strike the wings at a right angle to the line of their faces; but any direction of wind-motion will be almost as eifective as if it came at such right angle. The structural features of these wings permit them to coact with the hood to the end above stated.

The hood or top of my ventilator is of novel construction and coacts with the wings aforementioned in the draft-inducing and windconducting function. Each of the corners of hood is depressed, and between each of grooves the hood is arched, as shown in Fig. 1 at F. The arrow S in Fig. 2 shows the direction of draft from the chimney. The remaining arrows in this figure and in Fig. 1 show the direction of the draft-inducing currents. The hood F is supported on the member D by the supports E E, Fig. 1. The arch F of the hood coincides with the arched wing O of the wings already referred to. This relative position of these parts forms a wind-guide and conducts the external air in the direction of the arrows already referred to.

I do not limit myself to the exact specific structure set out, but might make modifications without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a ventilator of a line adapted to be mounted on a chimney, an outwardly and downwardly directed wind-conductor, with an air-passage between the flue and conductor, mounted on said flue, a secondary outwardly and downwardly directed wind-conductor mounted on the former, with an air-passage between the said conductors, and an outwardly and upwardly expanding member connected with the latter conductor and supported thereby, a series of wings O, 0

carried by said member, and ahood or covertending wings projecting from its upper end, the said member being carried by the latter conductor, and a hood or covering supported by said wing-carrying member, as and for the purpose 'set forth.

Signed by me at Philadelphia, Pennsy1va-' nia, this 30th day of June, 1899.

EDWIN O. ROYER ing therefor, having a series of wings up Witnesses:
